Ive got a PC with Biostar N325-A7, 1 gb of Gskill ram, 90 gb SATA HD, Radeon 9600, and AMD Athlon Processor.
|
My problem is: When I plug in the 20 pin connector, and flip on the power supply it is automaticly powering up my system. Completely ignores the power button on the case (even with the power button unplugged it continues). It goes straight to blank screen, and strangly, doesnt make any beeps. I removed a lot of the hardware to try and force a beep from it, still nothing. I have tried multiple PSU's, Vid cards, and ram.

It's an older board and ive heard of people having this problem. ALSO on the 20 pin plug in on the PSU (the PSU I was using when I started having problems) Some of the pins have burn marks on them. IT may be related. I'd appreciate any help possible before I get another MB.

Also no capacitors are leaking or bulging

Sound's like the motherboard is fried. Why were you messing with the 20-pin connector? Did you just build this computer?

Oh, heh, I was having previous problems with my PC turning off at random times. I thought it was the power supply so I tried a different one and then this happened. Oh man and the old PSU made the WORST whining noise ever.
